Thanks for the quick response!
Kindly see the schematic. Phase 1=fluid; Phase 2=solid.
In this case, I am denoting heat flux as BC to phases 1 and 2. However, I wish to ask further if a convective BC and heat flux BC could be applied separately to the left side of the wall also to different phases?.
I need to utilize the temperature (T_wall) obtained from the solver and implement it in the UDF. How can it be done? Of course, I need to decouple the walls for such an operation?
